iam building a box will 41 INCHES BY 21 INCHES BY 22 " be fine for the sub and how many cubic feet would that be thanks for any help !!

That would be 9.1 cubes before port and sub displacement (and bracing). So you should be ok. What port do you have in mind?

thats good to hear i was getting a lil scared i built it to big thanks man and the ports i will have two both at 21"by4" will that be ok u think?

Width x depth x height / 1,728 = Cubic feet (internal volume)

You will need to subtract your speaker, port and internal bracing displacement.
